AceShowbiz - Jay Garrick (%cTeddy Sears%) will return in "The Flash" / "Arrow" crossover, but how he will become part of the storyline was not really clear until now. Sears who plays the Speedster has shared details of Jay's return in the upcoming episode.
"Jay is summoned to S.T.A.R. Labs in an urgent matter from Wells (%cTom Cavanagh%)," he tells EW. "Jay shows up only to find out that Wells wants Jay to be his guinea pig. He is toying with a substance that has its history in the lore of The Flash, so it's something from the comics. He wants to try it on Jay to see if it works because he wants to use this on Barry in their fight to bring down Zoom."
But things won't work as Harry plans. "Jay doesn't react very well to that," Sears continues, "He doesn't want to be a part of Wells' schemes. There will be some life threatening moments in there and we have to use a combination of science and ingenuity and Wells' mysterious substance to get to a safe conclusion."
If Harry manages to give Jay the serum, Jay may get his powers back. Whether this happens or not, you will have to tune in to "Legends of Today" which will air Tuesday, December 1 at 8/7c on The CW. In the episode, Barry (%cGrant Gustin%) and Oliver (%cStephen Amell%) team up to fight against Vandal Savage (%cCasper Crump%). The said outing will also introduce Hawkgirl (%cCiara Renee%) and Hawkman (%cFalk Hentschel%).
